open it. The present invention has 'among' other objects to provideavalve which will not stick and which can be easily and quickly opened.The invention has other objects which are more particularly pointed outin the following description.

Referring now to the drawings: Fig. 1 isa sectional view taken on line 11 of Fig. 2 showing one form of valve embodying the invention. j j' Fig.2 is an end elevation of the valve shown in Fig. 1 with parts brokenaway.

Fig. 3 is a plan View of the valve shown in Fig. 2.

' Fig. 4 is of Fig. 2. Y Like numerals refer to like parts throughoutthe several figures.' f

Referring now to the drawings, I have shown a construction wherein thereis a valve casing 1 having a passageway 2 extending therethrough.Connected with the casing is a hollow cylindrical portion'4'which ispreferably at right angles to they casing 1. The casing 1 has a conicalseat which is concentric with the hollow cylindrical portion. Lo-

cated within the casing 1 is a closing piece 54 which is preferably ahollow cylindrical close Y ing piece, and I have shown it in the formofa truncated cone. This closing piece ts theconical seat and extendsacross the passageway through the casing when in its `closed position,the end thereof projecting into a recess 6 in the bottom of .thevalvecasing.; In the top of the closingpiece is a threaded opening inwhich works athreaded stern 7 the closing piece 5 provided at kits topwith a cylindrical projection smaller in diameter than the closingpiece, which is also provided with a threaded opening.' "The recess 6 islarger in cross section than the end of the closing piece 5 as shown inFig. 1. The hol-V low portion 4 has a cover 8 which hasa threadedportiony 9 which engages threads in the hollow portion 4. Thecover .8 isproa sectional view taken .on line'v anv kopening through whichl stem7fpasses. This stem hasan annular- Y 'Y shoulder` 10 which engages thecovery 8 vsofas,

to v"prevent the stemgfrom moving longitudinallyofr axially. yThe cover-Shasa recessll i-n v.which fits the threaded pack-ing piecei12,-l

u The stem 'Z .isjprovidedgat thettop',with some inea-ns forgturninf it..v -As herein'lshownp threaded to the top ,of the cover 8, there'kb'el-jand the cover Sand surrounding y' suitable means maybe used,such as the ordinary kvalve handle. c The l closing piece. 5 y 1sprovided with a groove 15., (see Figs. 2r-and 4);. This groovepreferably extends; the Vlength thereof.v lrojecting into thisgroove isa1 holding piece 16 which .permits `theclos k ing piece to bemoved;axiallybutprevents its rotation. In the particular n constructionshownthisholding piece isfapscrew;

Means is provided for preventing the locking of the closing piece 5 bythe screw 16,A

and for also preventing the engagement of the screw 16 with the bottomof the groove 15 so as to exert pressure thereon and make it dilicult toopen and close the closing piece.

In the particular construction shown twov v ymeans for accompli-Shingthis are provided.V f f5.5Y .15;- smaller than the bodyv thereof,the en-One consists in making the end of the screw larged threaded portionengaging shoulders pressure is exerted yon the bottom of the groove,Vand the other consists of the head :of the screw engaging the casing 1,or 1in. Y :t thisparticularA instance a washer, the 'casing 'having aprojection, as clearly shown in Figs. 2 and 3, for the engagement of thehead of the screw.

Since the closingpiece has an inclined or conical shaped faceand has its l large endupward it lifts easily and there can be no sticking. When it isdesiredtoV golose the `closing piece, the stem is rotated in theopposite `direction and the closing piece is Inove'dvdownto the closedposition shown inF-ig. l or to any intermediateposi.` tion.. v n ,f 10 Ihave described nrdetal a particular con struction embodying theinvention but" it i-s ofcourse evident that the parts may be Vai-n-`ried in many particulars Without departing i J from the spirit of theinventionas'embodied f l V115 in-,the claim hereto appended and AItherefore do not limit myself tothe particular con!
